How do people  influence the quality of air in Nysa, Rotterdam, Buzet and Pavlodar?
Jak ludzie wpływają na jakoś powietrza w Nysie, Rotterdamie, Buzet i Pavlodar?

Hypothesis: Quality of air in city depends on 3 different factors: number of people in the area, temperature and material used in furnace.

# data[].attributes.body
In our opinion results are answering the research question. People have huge influence on the quality of air and of course the pollution will be higher in bigger cities like Rotterdam or Buzet than in small town like Nysa. The application called Airly shows good details about atmosphere so we don’t see any sources of error. Nysa doesn't a have big population (it’s around 50 thousands people) so bigger towns should have bigger pollution and more gasses will be emitted into the atmosphere. On street Rodziewiczówny the results of humidity and air pressure are lower in the middle of the graph when the temperature is under 0 degrees Celsius. Particule matter depends on season and humans habits.

St. Rodziewiczówny, Nysa: The street is on the outskirts of town. The street is covered with asphalt and sidewalks. There are housing estates nearby. To the north of the observation point there is a city park 800 meters away, and to the south there is a Castorama at a distance of 1500 meters. To the west of the observation point there is the Rodziewiczówny housting estate at the distance of 100 meters, and to the east there is school 40 meters away.

It is much colder in Poland during winter than in the summer. Polish weather is rather long-lasting, for example sometimes it rains constantly for a few days or even more.

Data was collected by using application Airly. The measurements was taken twice daily at 9 AM and 9 PM by three weeks since 29.11.2019 to 19.12.2019. The app can measure temperature, air pressure, humidity and particulate matter (PM 10; PM 2,5) We didn’t use any kind of mathematical calculation which could be applied to analyze the data.

How do people influence quality of air in Nysa?

Goal of the research is to find out how quality of air within a day and longer period of time. The meansurements could raise awareness about pollution in atmosphere. Maybe in future people will try to prevent this.

To measurments we have used app called Airly and GPS in a cellphone.

The measurments were done every day on 9AM and 9PM. We were checking number of particles in the air, temperature, air pressure and humidity. Later, we wrote the data from a few days, analysed it and we turned them into graph available in Padlet app. The measurements had done from street Celna for nine days, but from street Rodziewiczówny for three weeks.

Street Celna

Most important data was from 10 and 11 december 2019, where you can find most visible corelation beetwen temperaturę and air quality. Day by day, the temperaturę has dropped about 3 degree Celsius and the number of particles have risen about 50%.

Street Rodziewiczówny
Results shows that highest pollution is when air temperature is lower. The air pressure and humidity don’t change radically. The worst air quality was 04.12, 05.12, 11.12 and 18.12 about 9 PM

It shows that temperature has influence on quality of air, because the lower it is, the higher is demand on furnace fuel, to warm houses. It causes increase in pollution, because in a lot of houses, people still using low quality furnaces and used trash like: plastic or rubber to heat them. In winter more people use different types of transport when they need to go somewhere. Car exhaust contributes to air pollution. I think that in the evening pollution is higher, because everyone just try to get home.

We need to encourage people to learn about quality of air and how they can change it. People should see the research like this to understand how impact they have to the atmosphere.

Key words: air, measurments, temperaturę, trash, furnaces

We find out that quality of air drastically lowers during winter, so that gave us first hint why that happens. During winter air quality in Nysa is really bad. It is not on a level of cities like Łódź or Huta in Cracow, but it is really close. During summer quality of air in decent.
For a few years, Winters in Nysa are not that strong like they used to be. Temperature often is above -10 degree Celsius. That causes people do not need that much heat in their houses. Usually they need to heat during evening and nights. For a most day the temperature on Celna street and Rodziewiczówny street was higher than 0 degree of Celsius the highest temperature was 9 degrees of Celsius. So when that happened, quality of air was the best. Around 10 to 20 PM per m³. But when temperature was lower, quality of air also lowered. So we have seen the corelation beetwen temperature and air quality. All od data confirms that theory.

The result are important because they affect our health. Quality of air sometimes is that bad, that it is better to stay at home, than go for a walk. It would be better for our health. Application was showing notification when the air was really polluted, and suggested to stay at home.

We need to focus on that to inform people so that they are aware of their actions. Heating with trash only can cause worst situation, and they are not aware of that. And also trash is not that effective like coal or wood. And quality of furnaces matters a lot. They are often old and used very much. That causes it needs more fuel because it can lose much more heat than deliver.  A lot of old furnaces also doesn’t have proper filter which also affects air quality. Moreover car exhaust have huge impact to affection of the air.

People could watch some documentary video about pollution to raise awareness, restrict heating in homes, use public transports or walking.

Protocols that we used:
- Test protocol for atmosphere pollution
- GLOBE atmospheric test protocol- description protocol of the atmospheric test site

Data was collected using application called Airly, using GPS from a cellphone. The app can measure pollution of air, moisture, temperature and air pressure. Data was collected daily on 9AM and 9PM by two weeks. Information written on the protocol was from eight days between 12.5.2019 and 12.13.2019.

# data[].attributes.body
St. Celna, Nysa: Highly urbanised street near city centre. Lack of trees causes high temperatures during summer and much lower during winters. The street is under renovation. Before and after renovation the street will be covered with asphalt, sidewalks with a little amount of grass and low housing.
